Apple unveiled its pricing plan for extended iCloud storage at today's developers launch. An extra 10GB will cost $20/year, more 15GB will be $40/year, and an extra 50GB (for a total of 55GB) will put you back $100 annually. The additional storage is available for purchase via the iOS 5's settings app. Apple users will get 5GB free to start and Photo Stream images will not count against capacity totals. [9to5Mac]
